Thermochromic Clock

July 18th, 2011

You could say that the “Thermochromic Clock” by CW&T looks like any other 4-digit 7-segment timepiece, but this one just works quite different.

Each segment in the display is made with a length of nichrome wire and then covered by a thick layer of black thermochromic paint. Time is displayed by applying voltage to the nichrome wire. As the wire sustains an electric current, it heats up the surrounding thermochromic paint, causing it to become transparent.

I want one.
